Running the red light 

Fucking a girl in the vagina when you know that she is on her period. Usually not a good idea. When in this situation, simply go home and start shaking hands with dr. Jolly

Yesterday things got heated and she told me she was on her period but, I just went running the red light anyway. Man I shoulda just went home and shook hands with dr. Jolly

shaking hands with dr. Jolly

Runnin' the red light 

1. A comedian who ignores the red indicator light and goes past their time slot on stage.

2. Refers to a person who orchestrates prostitution.

3. A phrase suggesting that someone lives dangerously.

1. I flashed Jerry the red light a few times to give him a two minute warning but he ignored me, running the red light.

2. The pimp has been runnin' the red light district down town for five years and then some.

3. Darnell is too daring, he's runnin' the red lights with his life all the time. That's dangerous for my taste.
